    Multimodal Interaction Flow Representation for Ubiquitous Environments - Mif: a Case Study in Surgical Navigation Interface Design
    (Springer Verlag, 2015) Altun, G.; Cagiltay, N.E.; Maras, H.H.; Borcek, A.O.; Tokdemir, G.
    With the advent of technology, new interaction modalities became available which augmented the system interaction. Even though there are vast amount of applications for the ubiquitous devices like mobile agents, smart glasses and wearable technologies, many of them are hardly preferred by users. The success of those systems is highly dependent on the quality of the interaction design. Moreover, domain specific applications developed for these ubiquitous devices involve detailed domain knowledge which normally IT professionals do not have, which may involve a substantial lack of quality in the services provided. Hence, effective and high quality domain specific applications developed for these ubiquitous devices require significant collaboration of domain experts and IT professionals during the development process. Accordingly, tools to provide common communication medium between domain experts and IT professionals would provide necessary medium for communication. In this study, a new modelling tool for interaction design of ubiquitous devices like mobile agents, wearable devices is proposed which includes different interaction modalities. In order to better understand the effectiveness of this newly proposed design tool, an experimental study is conducted with 11 undergraduate students (novices) and 15 graduate students (experienced) of Computer Engineering Department for evaluating defect detection performance for the defects seeded into the interface design of a neuronavigation device. Results show that the defects were realized as more difficult for the novices and their performance was lower compared to experienced ones. Considering the defect types, wrong information and wrong button type of defects were recognized as more difficult. The results of this study aimed to provide insights for the system designers to better represent the interaction design details and to improve the communication level of IT professionals and the domain experts. © Springer International Publishing Switzerland 2015.

    Guis With Haptic Interfaces
    (Springer Verlag, 2015) Ozcelik, E.; Tuner, E.; Sahin, H.; Tokdemir, G.; Arda Aydin, M.; Cagiltay, N.E.
    While there are many studies regarding utilization of Haptic feedback to enhance desktop GUIs and utilizing Haptic devices as additional interfaces to improve performance in current interaction techniques, there are not many studies that uses Haptic device as a primary input device. In this study, we present an experimentation conducted with 30 students, comparing performance of a Haptic device with mouse to use a GUI elements commonly used with mouse gestures. This study is inspired by a system that utilizes both mouse and a Haptic device, thus also taking task switching into consideration. We conclude that it is possible to achieve an acceptable performance with a Haptic device in a desktop-like GUI but further study and experimentation is necessary. © Springer International Publishing Switzerland 2015.

    Designing Games for Improving the Software Development Process
    (Springer Verlag, 2015) Yilmaz, M.; Kosa, M.
    With the proliferation of relevant technologies that enables interactive social engagements, games became a strong driving power for next generation social environments. One of the reason for this is that there is an engaging nature in both digital and non-digital games, which is also suitable for creating serious kind of interactions such as teaching, training, learning, etc. Recently, researchers have started developing games or game-like applications in particular domains such as education, management, medicine. Although there are loads of empirical studies about game-based learning in general, scholars from information systems, computer science and software engineering domains have only a few attempts to develop and use the specific properties of games in their context-dependent environments. This workshop paper takes a look at some of these efforts and discusses about the pros and cons of such approaches. It is also argued that using well-designed, validated and pertinent non-digital games could be beneficial for improving the software development process. In particular, such approaches can be transformed into useful tools for teaching information systems and software engineering undergraduate or post-graduate students the fundamentals of information systems and software engineering. © Springer International Publishing Switzerland 2015.

    Analysis of B2c Mobile Application Characteristics and Quality Factors Based on Iso 25010 Quality Model
    (Springer Verlag, 2014) Tokdemir, G.; Cagiltay, N.E.; Erturan, Y.N.; Yildiz, E.; Bilgen, S.
    The number of mobile applications in mobile market has rapidly increased as new technology and new devices are emerging at remarkable speed which shows mobile applications have an important role in every field of our life. Among those, even some of the mobile applications have a long time life as end-users use those effectively, some of them fail to do so that prevents the companies to reach from their aim. The main reason of that problem results from the quality of the mobile applications. Although there are some methods and metrics to analyze the quality of mobile applications, they have lack of criteria since they are mostly based on ISO 9126 quality model factors which are invalid anymore. This study aims to analyze both mobile commerce applications' characteristics and quality factors and sub-factors based on ISO 25010 product quality model. Accordingly a quality model is proposed by analysis performed by a group of experts from the mobile software development area. The results of this study aims to help developing more qualified and effective mobile applications from developer perspective. © 2014 Springer International Publishing.

    An Exploration of Individual Personality Types in Software Development
    (Springer Verlag, 2014) O'Connor, R.V.; Clarke, P.; Yilmaz, M.
    Previous research - using conventional psychometric questionnaires - has highlighted the importance of aligning compatible personality types in software development teams. However, there does not exist a dedicated, robust questionnaire instrument for revealing the pertinent personality types for software development practitioners. This study analyzes the validity and reliability of a 70-item (context dependent) personality-profiling questionnaire particularly developed to assess personality types of software practitioners. A systematic process of validation, using an iterative approach to questionnaire development, was employed. The questions were developed both with a qualitative analysis of interview data, and based on the opinions of expert reviewers who revised the items through a set of examination. To investigate how stable the questions and reproducible the results, we measured test-retest reliability of the instrument, yielding satisfactory results. The present study provided evidence for the construct validity of the instrument. Ultimately, an initial comparison of the results delivered by the instrument demonstrated positive correlations with the findings acquired with well-known personality assessment instrument, i.e. the big five personality questionnaire. © Springer-Verlag Berlin Heidelberg 2014.

    A Machine-Based Personality Oriented Team Recommender for Software Development Organizations
    (Springer Verlag, 2015) Al-Taei, A.; O’Connor, R.V.; Yilmaz, M.
    Hiring the right person for the right job is always a challenging task in software development landscapes. To bridge this gap, software firms start using psychometric instruments for investigating the personality types of software practitioners. In our previous research, we have developed an MBTI-like instrument to reveal the personality types of software practitioners. This study aims to develop a personality-based team recommender mechanism to improve the effectiveness of software teams. The mechanism is based on predicting the possible patterns of teams using a machine-based classifier. The classifier is trained with empirical data (e.g. personality types, job roles), which was collected from 52 software practitioners working on five different software teams. 12 software practitioners were selected for the testing process who were recommended by the classifier to work for these teams. The preliminary results suggest that a personality-based team recommender system may provide an effective approach as compared with ad-hoc methods of team formation in software development organizations. Ultimately, the overall performance of the proposed classifier was 83.3%. These findings seem acceptable especially for tasks of suggestion where individuals might be able to fit in more than one team. © Springer International Publishing Switzerland 2015.
